Information in this document applies to any platform.

Symptoms

When subsequent PS Plan is launched on a Past Due WIP Work Order; Operations which continue between the weeks ie Starts in One Week and Ends in another Week are scheduled during Weekends, though the Resource Capacity is not scheduled for Weekends.

Example
A Work Order has 3 Operations as below:
Operation 10 - Start Date 21-Jul 11:02:24 End Date 27-Jul 15:32:24
Operation 20 - Start Date 27-Jul 15:32:24 End Date 03-Aug 10:32:24
Operation 30 - Start Date 03-Aug 10:32:24 End Date 09-Aug 15:02:24

Operation 10 started on Friday 21-Jul 11:02:24 and is scheduled to run till Thursday 27-Jul 15:32:24 for 32 Hours and then the subsequent Operations. However, when PS is re-run on Monday, though PS considers the Actual Start Date of the Operation 10 same as determined earlier, it considers the Weekends as Working Day (Delay Time is defined), entire of 24 Hours and finishes the Operation by Monday 22-Jul 07:02:24 itself and shifts the 2nd Operation which was supposed to start on Thursday 27-Jul 15:32:24 to Monday 24-Jul 11:27:00.
